" NITTED STATES PATENT OFFICr- ALBERT HENTZ, OF NET/V YORK, N. Y.

COMPOSITION FOR REMOVING CORNS, 800.

SPECIFICATION forming part of Letters Patent No. 304,729, datedSeptember 9, 1884-.

Application filed September 14, 1881. (No specimens.)

To all whom it may concern.-

Be it known that I, ALBERT HENTZ, residing at New York, in the countyand State of New York, have invented a new and useful Improvement inCompounds for Removing Corns and Warts and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The object of the invention is to furnish a safe, reliable, andeffective compound for removing corns, warts, and other callosities ofthe skin; and the essential feature of the invention consists incombining collodion with salicylic acid, anodynous substances beingadded to produce a compound perfect in every particular.

I prepare my compound according to the following formula: Solublegun-cotton, three hundred parts; ether, six thousand five hundred parts;alcohol, two thousand two hundred and fifty parts; salicylic acid, onethousand two hundred and fifty parts; hydrochlorate of morphia, twentyparts; extract of In dian hemp, two hundred parts; water, three hundredparts. Total, ten thousand eight hundred and twenty parts.

Oollodion, being a solution of guncotton in ether and alcohol, will beused as the term embracing the first three substances given in the aboveformula.

The'compound is prepared by dissolving the various solids and agitatingthe different substances until thoroughly mixed. It is then put up inwell-stopped bottles, in order to prevent the evaporation of the etherand the thickening of the compound.

Referring to the rationale of the invention or action of the compound,it may be said that salicylic acid is the active agent, and collodionthe vehicle for applying the same to the skin, afilm or artificialcovering beingformed by the collodion for permitting the action of thesalicylic acid to go on underneath,

The compound is applied to the corn or other callosity of the skin bymeans of abrush, and, as the ether evaporates very quickly, a

film is left adhering to the skin. This film forms an artificialcovering for the corn, and holds the salicylic acid in contacttherewith, so that a gradual absorption of the salicylic acid by thecorn will take place. This will tend to loosen the corn in its seat, andafter a few applications of or periodical uses of the compound the corncan be easily removed. The drying action of the salicylic acid upon thecorn serves to loosen the same.

The liquid compound applied to a hard ened collodion film will dissolvethe same and cause the gradual absorption of the salicylic acid to takeplace by successive applications of the compound in the manner alreadystated.

The hydrochlorate of morphia and extract of Indian hemp, which enter asingredients in the compound above described, serve to allay pain, andtheir use tends to make the compound more perfect and satisfactory thanif no anodyne were contained therein.

-I am aware that collodion has been variousl y medicated, and thus madethe vehicle of several medicines for external application; but I am notaware that salicylic acid has ever been combined therewith as proposedby me.

WVhat I claim as new, and desire to secure by Letters Patent, is-

l. A compound for removing corns and other callosities, consisting ofthe active agent salicylic acid, and the vehicle or fixing agentcollodiou, as and for the purpose herein set forth.

2. A compound for removing corns and other callosities, consisting ofthe acth'e agent salicylic acid, the vehicle or fixing agent col-1odion,.and an anodyne, as and for the purpose set forth. I

v 3. A. compound for removing corns and other callosities, consisting ofcollodion, salicylic acid, extract of Indian hemp, and hydrochlorate ofmorphia, in or about the proportions specified.
